I have personally tested this currency exchange program called UniEx .
Support exchange between these currencies: Bitcoin:BTC:, BitcoinCash, Dash:DASH:, Litecoin:LTC:, Dogecoin:DOGE:, Perfectmoney, WEX, Paymer, Payeer, EXMO, Zcash.
And what I like about this company is the minimum required for most of the transactions of just $1. That's awesome!
